| Marketable Securities, Policy [Policy Text Block]                               | Marketable Securities: Marketable securities consist of publicly-traded equity securities that are classified as available-for-sale securities and investments in mutual funds that are classified as trading securities. On the balance sheet, available-for-sale securities and trading securities are classified as other current assets and other assets, respectively. The following table summarizes the components of the balance of the Company's available-for-sale securities at December 28, 2013 and December 29, 2012 (in millions):  December 28, 2013 December 29, 2012Adjusted cost$7 $9Gross unrealized gains28 32Fair value$35 $41Available-for-sale securities are reported at fair value based upon quoted market prices (see Note 13). Unrealized gains and losses, net of related incomes taxes, are recognized in accumulated other comprehensive income in shareholders' equity. Upon the sale of an available-for-sale security, the unrealized gain (loss) is reclassified out of accumulated other comprehensive income and reflected as a realized gain (loss) in net earnings. Realized gains (losses) are computed using the specific identification method and recognized as other expense, net. During both 2013 and 2012, the Company sold available-for-sale securities, recognizing pre-tax gains of $13 million and $14 million, respectively (see Note 10). There were no realized gains (losses) from the sale of available-for-sale securities recorded during fiscal year 2011. Additionally, when the fair value of an available-for-sale security falls below its original cost and the Company determines that the corresponding unrealized loss is other-than-temporary, it recognizes an impairment loss to net earnings in that period. There were no available-for-sale impairment losses recognized in fiscal years 2013, 2012 or 2011.  The Company's investments in mutual funds are reported at fair market value based upon quoted market prices (see Note 13) and are held in a rabbi trust, which is not available for general corporate purposes and is subject to creditor claims in the event of insolvency. These investments are specifically designated as available to the Company solely for the purpose of paying benefits under the Company's deferred compensation plan (see Note 12). |

| - Definition
Disclosure of accounting policy for investments in debt and equity securities that have readily determinable fair values (marketable securities). At a minimum, the disclosure might address accounting policies for investments classified as trading, available for sale, or held to maturity and may include how the entity determines whether impairments of available for sale or held to maturity investments are other than temporary, how the fair values of the entity's securities are determined, and the entity's accounting treatment for transfers between investment categories.
